Tips before you go

Frequently asked questions

How much does a smog check cost in California?

Each station sets its own test price, so call ahead. California also charges an $8.25 smog certificate fee for every vehicle that passes; ask whether the quoted price includes it.

Do I need a STAR station?

Your DMV renewal notice tells you. If it says "Smog Certification Required at STAR Station", only a STAR-certified station can certify the car. Otherwise any licensed smog check station can test it.

How long is a smog certificate valid?

A passing smog certificate is valid for 90 days.

Which vehicles are exempt?

Gasoline vehicles 8 model years old or newer pay a smog abatement fee instead of testing. Electric vehicles, motorcycles and gasoline vehicles from 1975 or earlier are exempt.
